Custom controls

You can create custom controls and implement custom logic for user interface elements. A good custom control is abstract, self-contained, and recurring.

A Slide Toggle is a good example of a custom control:

  • It’s abstract. You use it to switch between one setting and another.
  • It’s self-contained. You give it a label and an initial value. A Slide Toggle triggers an event when its state changes.
  • It’s recurring. You can use it in multiple places in an application.

The menu bar of your application isn’t a good example of a custom control:

  • It’s not abstract. It’s specific to your application.
  • It’s not self-contained. It probably has dependencies to other parts of your application.
  • It’s not recurring. There is probably only one menu in your application.

After you have created a custom control, you can style it with USS, add logic to handle events in C#, and expose and use it in UI Builder.
